Cell phones

Electronic or radio-controlled doors in jails

Other electrical devices

Conducting an Extensive Investigation into Your Case

Some of these devices may cause errors in breath test results if the breath test machine shares a power circuit with the other instrument, and some may interfere because they are in use too close to the machine. It is important to have an experienced and knowledgeable Washington DUI attorney conduct a thorough investigation if you do not believe your breath test report accurately reflects how much alcohol you actually drank. This investigation can help determine whether radio frequency interference or another outside factor may have influenced your test result.

DUI Dismissed

I can't thank Linda and her staff enough for getting me through this scary situation unscathed - all I had to do was comply and behave myself. Her knowledge of the system and her legal relationships made it possible to get me out of my DUI completely unscathed after just a 2 year probation period. NO license suspension, NO SR-22 insurance, and NO blow and go. I know that my case may have been a rarity in Washington State, but she was able to make it happen. Thank you Callahan Law!

Brilliant!

Ryan and his team are amazing. I was out of state facing an issue that was haunting me for over a decade. I hired Ryan to sort out my mess and I can’t thank him enough for all his hard work. Because of Ryan’s efforts I have peace of mind and I can move on with my life. To say he far exceeded expectations is an understatement. I recommend Ryan English without reservation.

Best DUI attorney!

Stephen Grant was professional, straight forward, and compassionate during the worst time in my life facing a DUI. He spoke with me on the phone himself, first time I called, letting me know what I may be facing. Thru each step in this long awful process he advised with very detailed instructions and was always thinking ahead of the game. Stephen truly works hard to get you the best outcome possible for your situation and knows very well the legal process. I was always proud to have him represent me in the courtroom. You can't go wrong choosing Stephen and the rest of his team at Callahan law keep you on top of everything while battling a DUI.

Absolutely Terrific!

Being in the military I was very worried that my case would have huge impacts both in civil court and my military career not only did Megan get be all the way down to Negligent driving in the 2nd degree. She went above and beyond by writing a letter to my commander in the army that explained my situation and that a Negligent driving in the 2nd degree is a non alcoholic offense. Which let to me staying in the army! Would absolutely contact her again if I was ever seeking an attorney.
